Also disclosed are methods for the preparation of these compositions and detergent products comprising these compositions.

Description

  • The present invention relates to a composition comprising a mixture of alkoxylated mono-, di-, and triglycerides and glycerine, to methods for the preparation of this composition, to detergent compositions comprising this composition, and to the use of the composition as surfactant or co-surfactant in detergent compositions.
  • Most of the known detergent compositions use anionic, amphoteric and/or non-ionic surfactants to obtain a final product showing satisfactory properties in terms of detergency and foam profile. However, most of these compositions are generally not satisfactory regarding the problem of ecotoxicity and the irritation to the eyes and the skin.
  • EP 0 586 323 B1 discloses detergent compositions showing improved properties regarding the ecotoxicity and the irritation to the eyes and to the skin. These compositions comprise the mono-, di- and tri-ester compounds represented by the following formula, wherein the weight ratio of mono-, di-, and tri-ester is 46-90/9-30/1-15:
    Figure 00010001
    wherein R' represents H or CH3, B represents H or
    Figure 00020001
    wherein R represents an alkyl or alkenyl group having 6 to 22 carbon atoms, and each of m, n, and l may have a value between 0 to 40, the sum of m, n and l being in the range of from 2 to 100.
  • The viscosity of compositions disclosed in EP 0 586 323 B1 having a good foaming power is generally low. Although the viscosity may be increased when the alkoxylation degree is lowered, this is generally not preferred, since then the foaming power is also dramatically decreased. Therefore, a salt such as sodium chloride is generally added in order to increase the viscosity. However, adding a salt leads to an enhanced irritation of the skin and the eyes.
  • In view of this prior art it was the problem underlying the present invention to provide compositions showing a high viscosity and good foam stability, while also showing the good properties with respect to biodegradability and irritation to the eyes and the skin.
  • This problem is surprisingly solved by a composition comprising
  • (i) compounds represented by the following formula (I), wherein each of B1, B2 and B3 independently represent a group represented by the following formula (II);
  • (ii) compounds represented by the following formula (I), wherein two of B1, B2 and B3 independently represent a group represented by the following formula (II), the remainder representing H;
  • (iii) compounds represented by the following formula (I), wherein one of B1, B2 and B3 represents a group represented by the following formula (II); the remainder representing H;
  • (iv) compounds represented by the following formula (I), wherein each of B1, B2 and B3 represent H;
    • the weight ratio of the compounds (iii) / (ii) / (i) being 46 to 90 / 9 to 35 / 1 to 15:
    Figure 00030001
    R' representing H or CH3, and each of m, n, and l independently representing a number from 0 to 4, the sum of m, n and l being in the range of 1 to smaller than 2;
    Figure 00030002
    wherein R represents an alkyl or alkenyl group having 6 to 22 carbon atoms.
  • The weight ratio of the compounds (iii) / (ii) / (i) in the composition of the present invention is preferably 60 to 83 / 16 to 35 / 1 to 6.
  • Particularly preferred are compounds of formula (I) wherein R' in formula (I) represents H, that is, the compounds are ethoxylated derivatives.
  • The sum of m, n and l in formula (I) is preferably in the range of 1.5 to smaller than 2.
  • The weight ratio (i)+(ii)+(iii) / (iv) is preferably in the range of 85/15 to 40/60, more preferably in the range 80/20 to 45/55.
  • The compositions of the present invention can be prepared by a first method comprising the following steps:
  • a) Subjecting a mixture of glycerine and a compound of the following formula (III) to an interesterif ication reaction:
    Figure 00040001
    wherein R represents an alkyl or alkenyl group having 6 to 22 carbon atoms, and
  • b) subjecting the reaction mixture obtained in step a) to an alkoxylation using an alkylene oxide having 2 or 3 carbon atoms in the presence of an alkaline catalyst.
  • The interesterification reaction in step a) is governed by statistics. Consequently, the molar ratio of the compounds (i), (ii), (iii), and (iv) in the final product is determined by the ratio of the starting materials glycerine and the compound of formula (III). The subsequent alkoxylation reaction of step b) is a reaction which generally proceeds quantitatively, so that the amount of alkylene oxide used determines the alkoxylation degree (that is, the sum of m, n, and l). The molar ratio of the compounds (i), (ii), (iii), and (iv) is not affected by the alkoxylation, since the alkylene oxide only reacts with the remaining free hydroxyl groups in the mono- and di-ester molecules and the glycerine. However, the weight ratio of the compounds (i), (ii), (iii), and (iv) is consequently changed. Since the outcome of both reaction steps a) and b) can be predicted by the skilled person, modelling calculations can be employed to determine the correct ratio of the starting materials for a specific predetermined weight ratio of the compounds (i), (ii), (iii), and (iv) and a specific predetermined alkoxylation degree.
  • The compound of formula (III) includes natural fat and oil as well as synthetic triglycerides. Preferred is a fat or oil including vegetable oil such as coconut oil; palm oil; palm kernel oil; sunflower oil; rape seed oil; castor oil; olive oil; soybean oil; and animal fat such as tallow, bone oil; fish oil; hardened oils and semihardened oils thereof, and mixtures thereof. Particularly preferred are coconut oil, palm oil and tallow such as beef tallow.
  • Further, the composition of the present invention can be produced by a second method comprising the following steps:
  • a') Reacting a mixture of glycerine and alkylene oxide having 2 or 3 carbon atoms in the presence of an alkaline catalyst.
  • b') Reacting the reaction mixture obtained in step a') with a compound of the following formula (IV).
    Figure 00050001
    • wherein R is defined as above for formula (III) and X represents a methyl group or H.
  • The degree of alkoxylation in the final product (that is, the sum of m, n, and l) is determined by the amount of alkylene oxide employed in step a'). Step b') then determines the molar ratio and the weight ratio of the compounds (i), (ii), (iii), and (iv). Again, the outcome of both reaction steps a') and b') can be predicted by the skilled person, so that modelling calculations can be employed to determine the correct ratio of the starting materials for a specific predetermined weight ratio of the compounds (i), (ii), (iii), and (iv) and a specific predetermined alkoxylation degree.
  • The compound of formula (IV) is preferably derived from one of the fats or oils which are preferably used in the first method of the present invention and which are listed above. Particularly preferred are tallow fatty acid and coconut oil fatty acid, palm oil fatty acid, or a methyl ester thereof.
  • The composition of the present invention is preferably used as a surfactant or co-surfactant in detergent compositions in which they are preferably contained in an amount of from 0,5 to 20 wt.%, more preferably 1 to 8 wt.%.
  • The detergent compositions of the present invention may additionally contain one or more of the following additives, depending on the purpose of the detergent composition, this list being non-limiting.

  • As may be derived from the results above, when the ethoxylation degree is larger than 4 (Ex. J, M, N, O), maximum viscosity is always lower than 14000 mPas measured with a Brookfield viscosimeter at 20°C. When the ethoxylation degree is lower than 1 (Ex. K) viscosity is also lower than 14000 mPas. When the triester content is lower than 1(Ex. C; 90/10/0), maximum viscosity is also very low (lower than 14000 mPas). When the diester content is too high (Ex I: 40/46/17 and Ex L: 46/42/12), then the viscosity is also lower than 14000 mPas.
  • However, when the samples are within the alkoxylation degree in accordance with the present invention (1 to smaller than 2 EO mols), viscosities are considerably higher (see Table I). Specially this behaviour is enhanced when the EO mols are between 1.5 and 3 (Ex A, A', B, E, E', F, F').
  • Formulations containing the composition of the present invention are exemplified by the following:
  • The detergent compositions of the present invention may be formulated as shampoos, baby shampoos, conditioning shampoos, bath gels, hair conditioners, for manual dishwashing, and as all purpose cleaners which are exemplified below (all values indicated are weight percentages):
